INVENTOR- FRED M. CARROLL United States Patent WEB CUTTING AND FEEDING DEVICE FOR PRINTING MACHINES Fred M. Carroll, Binghamton, N. Y., assignor to International Business Machines Corporation, New York, N. Y., a corporation of New York Application April 30, 1952, Serial No. 285,134

3 Claims. (Cl. 101-227) This invention relates to printing devices and more particularly to means for preparing record cards having printed matter on reverse and obverse sides, from a Web of suitable material. 7

Due to the fact that record cards, more commonly known as tabulating cards, are used primarily for accounting purposes, they are required to be precisely accurate as to length and position of printed matter. As is well known by persons familiar with the art of preparing said cards, ordinary printing and cutting machines have not been found satisfactory. A highly satisfactory tabulating card printing machine which operates on a blank continuous strip of material to print record forms thereon which are cut apart to form card lengths, each with a printed form on one side of a card, is described in Patent No. 2,181,935, issued to Fred M. Carroll on December 5, 1939.

It is frequently quite desirable to have printed matter appear on both sides or faces of a record card. In accordance with the foregoing, it is the general object of this invention to provide an improved machine for rapidly producing record cards having printed matter on reverse and obverse sides thereof and stacking them in stacks for removal by the operator.

Another object of this invention resides in the combination of means for rapidly producing record cards having printed matter on one side thereof and novel means for rapidly removing said cards therefrom for printing on the reverse side of said cards.

A more specific object of this invention resides in the provision of improved means for stopping machine operation upon detecting a card jam.

Other objects of the invention will be pointed out in the following description and claims and illustrated in the accompanying drawings, which disclose by way of example, the principle of the invention and the best mode which has been contemplated, of applying that principle.

2,771,029 Patented Nov. 20, 1956 ice General description As the apparatus for operating on a blank continuous strip of material whereby record forms which are cut apart to form card lengths printed on only one side thereof, is described in detail in the aforecited Carroll Patent No. 2,181,935, the said apparatus will be described only briefly herein.

Referring to Fig. 1, a web of record card material 10 is fed off a supply roll 11, around a swivel-supported guide roll 12, through the slot of a thickness-detecting element 13, over a guide roll 14, around a tension-reacting roller 15, and between a guide roller 16 and a striping roller 17. The latter paints an intermittent stripe along an edge of the continuously feeding web. From the striping roller, the web passes around a roller 18, then between a roller 19 and a co-working plate (not shown, plate 39 of Fig. 11, Patent No. 2,181,935), around the corner of straightening block 20 along guide plate 21, past an emergency cutter (not shown, cutter 72 of Fig. 11, Patent No. 2,181,935), and into the grip of feed rollers 22 and 23. The latter feed the web through a printing couple 2425 which prints successive card forms on a single face of the web. The web then proceeds through plates of a jam detecting device (not shown, plates 87 of Fig. 1, Patent No. 2,181,935), then between rotary shear devices 26 and 27, and into a pair of vertical fluted rollers 28 and 29. As the web is moving upwardly, blades suitably attached to the rotary shear devices 26 and 27 coact with a scissors action to shear the web and form a separate tabulating card 30, now above the cutting blades. As the card continues its upward feed due to its own momentum and due to its being fed upwardly by rotation of the cutting blade upon which the card is resting, it is clamped by suitable clips on a conveyor drum 31 which continuously rotates in a counterclockwise direction. The cards thereon move past a hanging wire 32 to control movement of the wire in accordance with the degree of straightness of the cards. Wire 32 controls a switch 33 to control a solenoid for regulating the position of roller 19 and its co-working plate, thereby regulating the angle which the web makes with the straightener block 20. The straightening action is thus automatically adjusted in accordance with the sensing of the cards by wire 32.

The cards proceed past Wire 32 to a corner clipper (not shown) adjustable to clip either left or right-hand upper corner (see Fig. 32 of Patent 2,181,935). After passing the corner clipper, the cards cause a paddle wheel (not shown, wheel 193 of Fig. 18, Patent No. 2,181,935) to rotate so as to actuate a card counting mechanism.

After passing the card-controlled paddle wheel, the cards are released from conveyor drum 31 onto a table 38 which guides each card 30 toward feed rolls 39 and 40. As the description advances, the operation of the mechanism by which the saidcards are successively re leased from drum 31 onto table 38, and then fed singly from table 38 toward feed rolls 39 and 40 of the reverse side card printing mechanism, will be explained in detail.

The cards are advanced by feed rolls 39 and 40 past a printing couple 4142 toward feed rolls 43 and 44 which, in turn, advance the said cards toward a stacker plate 45. After a stack of cards has been acquired, such as the stack 46, an actuating mechanism to be described hereinafter causes conveyor belts 47 to move the stack away from stacker plate '45 to a position on the conveyor for removal therefrom by the operator.

Main drive mechanism Referring to Fig. power is supplied to the reverse side card printing mechanism! through a pair of bevel gears 51 and 52fixed to shafts 53 and 54,- respectively.

The idler gear that directly drives gear 390 (Fig. 3, Patent No. 2,181,935) is also mounted on the shaft 53. It may be seen by examining Fig. 3 of the aforecited patent, No. 2,181,935, that the link 382 is connected at its upper end to the base plate of the printing machine drive motor and at its lower end to the lever 383 having an arm 333a extending horizontally. Lever 383 is fixed to shaft 384 provided with a manual operating rod. When the printing machine is running, arm 383a is supported by the top of the vertical arm of the bell crank latch 386. In this position of arm 383a, lever 383 is at its counterclockwise limit, link 382 is raised so that power is applied from the drive motor to shaft 53 by means of a suitable gear train. Thus, the reverse side card printing mechanism; main drive shaft 55 which is connected to shaft 54 through a coupling 56, is rotated continuous ly during the entire time that the printing machine is operating.

Referring to Fig. 3, main drive gear 57 which is fixed to shaft 55 actuates gear train 58-62 to rotate the first set of feed rolls 39 and 40 (Fig. gears 58, 59, 60, 63, 6d, 65 and 66 to rotate feed rolls 43 and 44 (Fig. 5); and gears 58, 59, 60, 63, 67 and 68 to operate the printing couple 41-4-2 (Fig. 5). As is shown in Fig. 3a, gear 69 is attached to shaft 70 for rotation therewith in order to continuously rotate clutch disc 71 fixed to gear 72 through a gear train comprising gears 73, 74, 75, 76, 77, 78 and 72.

Card feed mechanism Referring to Fig. 6, before a tabulating card 30 reaches a horizontal position, the clip 85 carrying the card is re leased from the card and held released until the card drops by gravity onto table 38. The release of the clip from the card is effected by a stationary block 86 having an inclined cam surface 87 which meets the extension 88 of the clip 85, and earns the clip extension downwardly to rock the clip counterclockwise. This action of the clip frees it from the inner, or righbhand side of the card. Extension 88 continues to ride along the cam surface of block 86 to maintian the clip released from the card until the clip completely departs in a horizontal direction from the right-hand or inner end of the card. At the moment of release of the card, its clip 85 is passing through a slot formed within a vertical plate 89, and the card is substantially horizontal with its right-hand edge, 'at either side of the clip, abutting the extensions 90 and 91 (Fig. 5) of the said plate. Thus, as the clip continues its movement toward the right and passes freely through the aforesaid slot, the plate 89 positively prevents the card from following.

When the clip leaves the card, the latter drops with its left side edge guided by plate 92 and its right edge by plate 89. The said plates guide each card as it is pushed toward the first set of feed rolls 39 and 40 by card pushers 93.

As is shown in Figs. 5 and 6, a finger 97 is provided to hold the card against table 38 during the time that the pushers 93 are advancing the card towards the first set of feed rolls. The finger 97 is attached to a short shaft 98 freely mounted in a block 99 which is set at a suitable angle so that the finger will move downwardly as it is pivoted clockwise over the card on table 38.

The mechanism for rocking finger 97 once during each reverse side card printing mechanism card feed cycle is shown in Fig. 5. Cam follower 101 oscillates about shaft 102 under control of cam 103 fixed to main drive shaft 55. A bias spring 104 maintains continuous contact between earn 103 and the cam follower roller. As the tabulating card is being released from a clip 85 onto table 38 (Fig. 6), the cam follower roller is on the high portion of cam 103 and finger 97 is at the counterclockwise limit so as not to obstruct positioning of the card on the said table. Immediately thereafter the cam follower roller drops on the low dwell of cam 103, thereby allowing cam follower 101 to move in a clockwise direction so that finger 97 is pivoted in a clockwise direction over table 38 to position and to hold the card thereon. said finger positions the card on table 38 prior to the time that pushers 93 contact the edge of the card, and holds the card on the table until after the card is gripped by the first set of feed rolls 39 and 40. As is shown, finger 97 is rocked each card cycle by means of connecting links 105, 106 and 107, rod 108, and lever 109 fixed to shaft 98.

.As shown in Fig. 5, the card pushers 93 are in a position to contact the trailing edge of a card on table 38 in order to advance it to the first set of feed rolls 39 and Each of the said card pushers is pivotally mounted at a point 110 to an arm 11! which, in turn, is fixedly attached to a shaft 102 and resiliently connected to cam follower 112 through a spring 113. Cam follower 11.2. freely mounted on shaft 102, is caused to oscillate once each card feed cycle under the control of a cam 114 fixed to shaft 55. Continuous contact between cam 114 and the cam follower roller is maintained by a bias spring 115. During the time that earn follower 11.2 is pivoted in a clockwise direction about shaft 102 the said pushers are moved to the right by spring 113; however, during the time that cam follower 112 is pivoted counterclockwise and said pushers are positively moved to the left by an extension on follower 112. As the description advances, the purpose for having the resilient connection between follower 112 and arm 111 will be explained in detail in conjunction with the jam detecting apparatus. in order to allow more rapid operations,

means are provided for lowering the card pushers below i the level of table 38 during their movement to the left. Each pusher 93 is biased in a counterclockwise direction by spring 121 so that as they are moved to the right, contact is maintained between guides 122 attached to table 38 and a stud 123 on each pusher 93. Prior to the time that the pushers are moved to the left, stud 123 passes between the inclined portion of guide 122 and the inclined surface of a block 124 which is pivotally connected to a bracket 125 at point 126, and biased upwardly by a conventional spring means. As a result thereof, during the time that the pushers are moved to the left, each pusher stud 123 will ride on the under surface of its associated block 124 and the pushers will be maintained thereby beneath the level of table 38. The pushers are returned to the left a distance sufficient to permit the said studs to pass beyond each of the blocks 124 and into contact once again with each of the guides 122 in preparation for advancing a succeeding card.

Printing and inking apparatus As explained hereinbefore, each succeeding card on table 38 is advanced therefrom into the grip of feed rolls 39 and 40 by pushers 93. Referring to Fig. 5, the said feed rolls are fixedly attached to their respective feed roll shafts 127 and 128 to which continuously rotating gears 62 and 61 (Fig. 3) are also fixedly attached. Under control of the said feed rolls, each succeeding card is advanced into the printing couple 41-42 for applying printed data on the reverse side thereof.

The printing drum 41 comprises a printing plate 130 that is suitably attached to a cylinder 131 which, in turn, is attached to a shaft 132 for rotation therewith. As shown in Fig. 3, shaft 132 is maintained continuously rotating by the aforedescribed gear train which drives gear 68. Platen 42, fixedly attached to shaft 70 (Fig. 3), is also maintained continuously rotating by means of the aforedescribed gear train which drives gear 63.

Referring again to Fig. shaft 132 is supported for rotation by arms 133 extending from member 134 which is pivotally mounted on stub shafts 135 of the side frames on either side of the printing mechanism. Adjusting The I screws-140" (only one is shown) projecting through exto Fig 3, gears 143 and 144 are fixed to shaft1'32 for rotation therewith. As described hereinbefore, shaft 132 is rotated continuously by gear 68 which'is fixedly attached thereto and driven by the gear train actuated by main drive gear 57. Continuously rotating gear 144 actuates the gear train comprising gears 145, 146, 147, 148 and 149 fixed to their respective shafts 150, 151, 152, 153 and 154 for rotating ink carrying rolls 155, 156, 157 and 158 fixedly attached to shafts 159, 160, 153 and'154, respectively, shown in Fig. 8. Gear 143 (Fig. 3) actuates the gear train comprising gears 165, 166 and 167, said gear 167 being fixedly attached to shaft '168, for rotating cam 169 (Fig. 8) also fixed to shaft 168.

Referring to Fig. 8, a member 170, pivotally mounted on shaft 171, supports an ink reservoir 172, a plate 173and a shaft 174 to which ink roll 175 is fixed. As cam'169 rotates in a counterclockwise direction, cam follower 176 is caused to oscillate about stud 177 whereby transfer ink roll 178 supported by the said cam follower is caused to alternately contact ink roll 175 and ink roll 179. Rollv 178'is driven in a counterclockwise direction by the rolls'175 and 179 as their respective surfaces alternately make contact. A spring 180 connected, at one .end, to the main frame, and, at its other end, to a stud 181. attached to follower 176, biases the said follower counterclockwise. A pawl 185, freely mounted on stud 181, advances ink roll 175 each time that follower 176 pivots clockwise by engaging the teeth of a ratchet 186 fixed to shaft 174. Pawl 185 rides onaneccentric stud 187 which determines the relative position at which pawl 185 will engage ratchet 186, thereby regulating the amount of rotation imparted to ratchet 186 and controlling, in part, the amount of ink transferred from ink roll 175 to transfer roll 178. Plate 173 also aids the control of the amount of ink transferred from roll 175 to roll 178, and more particularly the control of the quantity of ink taken by roller 175 from the ink reservoir. 7

As a result thereof, a regulated quantity of ink is transferred from roller 175onto roller 179 by transfer roller 178. The said ink is distributed thereafter to continuously rotating metallic rollers 157 and 158 which, in turn, distribute the ink to rollers 155 and 156 making contact with printing plate 130.

The contact pressure between inking rollers 155 and 156, and printing plate 130 may be altered by varying the projection of adjusting screw 188 in extension 141. As is shown in Figs. 5 and 8, the extension 189 of the inking unit side frame 190 rests upon the upper portion of adjusting screw 188 in order that the said frame may be moved about shaft 191 as the projection of the threaded body of screw 188, supported by extension 141, is varied.

Ejecting and stacking mechanism The machine includes mechanism for grouping the cards in stacks of a substantially predetermined number and conveying the stacks separately on a conveyor for removal therefrom by the operator.

Continuously rotating gear 72 (Fig. 3a), has fixed to it a multi-tooth clutch disc 71 (Fig. 3), beside which is a clutch'disc 195 fixed to cam shaft 196 and having a clutch dog 197 pivoted thereon. The integral unit comprising gear 72 and disc 71 is freely mounted on shaft 196. The dog is normally disengaged by a latch 198, which can be released by the oblique flange 199 of a lever 201 fixed to a rock shaft 202. The other end of lever 201 is normally latched against the action of a spring 203 (Fig. 3) by an extension 204 of a latch 205 pivotally mounted on a stub shaft 206.

The latch 205 is normally held at the counter-clockwise limit of its movement by a spring 207, thereby extending member 208 to the left. I

Referring to Fig. 5, during the normal operation the cards which are fed out of the last feed rolls 43 and 44 come to rest upon a stacker plate 45 which is mounted upon a vertical support 209 and counterbalanced upwardly by a spring 210 connecting the base with a crank 211 joined to the vertical support 209 by a connecting link 212. As the weight of cards on plate 45 increases, the table will be lowered gradually until it strikes a lever 213 (Fig. 4) which is pivotally mounted on a frame member at connection 214 (Fig. 3); the extended operating end of lever 213 projects above the level of conveyor belts 47. As shown in Fig. 4, lever 213 is connected by a link 215 to a second lever 216 pivotally mounted on a frame member at connection 217. Therefore, as lever 213 is moved clockwise by stacker plate 45, lever 216 also pivots clockwise so as to raise member 208 into the path of a lug 218 on arm 219. Arm 219 is caused to oscillate once each card cycle by continuously rotating cam 220 (Fig.3) fixed to shaft 225, through a cam follower 226 and a connecting link 227. Thus, when member 208 is raised into the path of lug 218 as aforedescribed, the said member will be moved to the right during the time that the cam follower roller is on the high portion of cam 220, thereby unlatching lever 201 for-rotation under the action of spring 203. As a result thereof, flange 199 will engage an extended end 228 (Fig. 4) of latch 198 in order to unlatch dog 197 for engagement with the clutch disc 71.

In addition to the foregoing, the rotary movement of shaft 202 will cause an auxiliary card stacker plate 229, also fixed to shaft 202, to pivot into position to receive the cards fed from the last set of feed rolls 43 and 44 while the stacking cycle is in progress.

Referring to Fig. 5, the clutch having been tripped as described hereinbefore, cam shaft 196 will complete one revolution prior to being latched again. Cams 230, 231 and 232 (Fig. 4), fixedly attached to shaft 196, cause the following sequence of events: stacker plate 45 to be lowered below the surface of conveyor belts 47 in order that the card stack may rest directly upon the said belts; conveyor belts 47 to be moved to the right in order to carry the said stack therewith away from stacker plate 45; and the stacking mechanism to be restored to its latched condition. The foregoing will now be described in detail. A member 233, freely mounted on shaft 234, is connected to crank 211 by a shear pin 235. As cam 231 rotates in a clockwise direction, cam follower 236, attached to a cam follower roller 237 and a roller 238, pivots in a counterclockwise direction about shaft 239 on which it is freely mounted. This action causes roller 238 to act upon an car 240 of member 233 so as to lower stacker plate 45 below the level of conveyor belts 47.

The conveyor unit comprises a pair of driven rollers 245 fixed to a shaft 246, a pair of idler rolls 247 (Fig. l) and a pair of continuous conveyor belts 47 arranged in .a conventional manner around the said rolls. A gear sector 248 forming an integral part of cam follower arm 249 meshes with a gear 250 fixed to a ratchet wheel 251 (Fig.3), both of which are freely mounted on shaft 246. As cam 230 rotates clockwise, cam follower 249 is caused to oscillate about shaft 239 whereby gear 250 first rotates counterclockwise in order to permit dog 252 (Fig. 3), pivotally connected to roll 245, to engage ratchet 251, and then rotate clockwise so as to move the con-- veyor belts to the'right by means of the ratchet drive.

The belts are advanced sufficiently to carry the stack of cards clear of stacker plate 45. Thereafter, stacker plate 45 moves upwardly as the ear 240 follows the clockwise movement of roller 238.

Referring to Fig. 4, after the foregoing operation has been completed, the high lobe of cam 232 causes a cam follower 253 to rotate clockwise in order to latch lever 201 on extension 204, thereby permitting dog 197 to latch. The auxiliary card stacker plate 229, being fixed relative to lever 201, will be restored to a position away from the last set of feed rolls 43 and 44. The cards which have accumulated during the stacking operation are removed from plate 229 by a block 255 (Fig. and allowed to drop on stacker plate 45.

As stated hereinbefore, during the normal operation the cards which are fed out of the last set of feed rolls come to rest upon stacker plate 45. In order to assure proper stacking, means are provided whereby each succeeding card is positively placed on top of the card stack after the said card has been released from the grip of rollers 43 and 44 (Fig. 5). A stacker finger 260 and a card aligner plate 254 are each fixed to a member 261 which, in turn, is fixed to a spring biased lever arm 262. It may be seen in Fig. 3 that member 261 has fixed thereto a crank arm 263 which is caused to rock once each card cycle by means of cam follower 264 and connecting link 265 as cam 259, fixed to shaft 225, rotates. Referring again to Fig. 5, as member 261 rocks with arm 263, it carries along with it stacker finger 260 and aligner plate 254. The timing of this mechanism allows finger 260 to move counterclockwise against the side of a card just as the card is released from the grip of the last set of feed rolls 43 and 44, thereby positively positioning the said card on top of a stack of cards held by plate 45. Immediately thereafter, the said finger is moved clockwise so as not to obstruct the passage of a succeeding card being advanced by the last set of feed rolls, and the aligner plate 254 is brought into contact with the leading edge of the last card positioned on the said stack of cards so as to align the leading edges of all the cards in the stack.

Jam detecting device A jam contact and operating mechanism therefore are provided to stop the operation of the printing machine in the event that a card becomes jammed while being fed by the card pushers towards the first set of feed rolls.

Referring to Figs. 4 and 7, the normally closed contact 266 is mounted upon lever 267 which, with lever 268, is pivotally mounted upon a stub shaft 269 fixed to the main frame. The relative position of the said levers is controlled by the relative positions of their respective links 270 and 271 to which they are joined. Link 271 is fixed to connecting rod 272 which, in turn, is fixed to cam follower 226. Thus, lever 268 is caused to oscillate about shaft 269 once each card cycle. Due to the fact that lever 267 is resiliently connected to lever 268 by spring 273, lever 267 also rocks about shaft 269 once each card cycle. This action causes link 270 and jam detecting finger. 274 to pivot in a clockwise direction about stub shaft 275 as link 271 moves downwardly, and to pivot counterclockwise as link 271 moves upwardly. Lever 267 is positively driven in a counterclockwise direction by the action of lever 268 on lip 276.

As is shown in Fig. 6, the curved end of finger 274 moves beneath the card feed level, i. e., the level of card receiving table 38, during the course of its clockwise movement. in the event that a card becomes jammed while being fed towards the first set of feed rolls, finger 274 will be stopped at, or above, the card feed level during its clockwise movement. Referring to Fig. 4, it may be seen that stopping finger 274 will also stop lever 267 and contact 266 attached thereto. However, lever 268 will continue to pivot in a clockwise direction as link 271 moves downwardly. As a result of the foregoing, extension 277 of lever 268 will operate upon the lower contact strap to open contact 266. As to be explained hereinafter, this causes the printing machine to stop.

Referring to Fig. 5, the card pusher mechanism is re siliently connected to cam follower 112 by spring 113. If for some reason the forward motion of card ushers 93 is interrupted, e. g., a card jam, the pivotal movement of arm 111 will be stopped while that of cam follower 112 will continue.

As the reverse side card printing unit described herein is an auxiliary part of the printing machine described in the aforecited Patent No. 2,181,935, and the electrical circuit of the latter machine is explained in detail therein, the said circuit will be described only briefly herein to the extent that it is affected by the jam detecting contact 266.

Referring to Fig. 9, contact 266 is shown connected intermediate points 391a and contact 34 of the circuit shown in its entirety in Fig. 35 of the aforesaid patent. When a card jam occurs and normally closed contacts. 266 are opened thereby, the printing machine circuit is affected in exactly the samemanner as when normally closed contacts 34 are opened; namely, magnet 392 is de-energized so as to open the drive motor main line contacts 39% and 394d. In addition thereto, means are provided for permitting latch 386 (Fig. 2) to pivot clockwise, thereby withdrawing its support from arm 383a of lever 383. Consequently, the drive motor and its supporting base plate will drop sufficiently to loosen the printing machine driving belt. As a result of the foregoing, the driving connection of the drive motor to the gearing of the printing machine is released while at the same time the motor, its circuit having been broken, coasts to a stop.

While there have been shown and described and pointed out the fundamental novel features of the invention as applied to a preferred embodiment, it will be understood that various omissions and substitutions and changes in the form and details of the device may be made by those skilled in the art, without departing from the spirit of the invention. It is the intention, therefore, to be limited only as indicated by the scope of the following claims.

What is claimed is:

l. in a machine for forming record cards from a web having means for printing successive impressions on one face of the web, and means for cutting the web into separate cards, each bearing a single impression; the combination of a card receiver having a receiving bed and a pivotally mounted card stripping and depressing element arranged to be oscillatable over said receiving bed; a continuously operating rotary conveying mechanism for gripping one edge of a card after being cut and, during turning, correspondingly turning the card into position for reception by said receiver, said receiving bed thereof arranged in the plane of rotation of said conveyor mechanism so that each card gripped thereby is moved directly into said card receiver; means for oscillating said card stripping and depressing element in a timed relationship to said rotary conveyor mechanism so that said stripping and depressing element is moved away from and out of alignment with said receiving bed to be ineffective during the period of movement of a card from said conveyor mechanism into said card receiver and is moved towards and into alignment with said receiving bed to be effective immediately thereafter so as to position each succeeding card onto said receiving bed; a rotary printing means adjacent said card receiver for printing impressions on the reverse face of each succeeding card; card feeding means including reciprocable card pushers for acting upon the trailing edge of a card in said card receiver so as to advance the card from said card receiver to said rotary printing means; means for rendering said card feeding means operative in a timed relationship to said rotary conveyor mechanism so that a card. is pushed from said card receiver during the period that said stripping and depressing element is effective to position the card onto said receiving bed; means for normally maintaining said vpushers above the surface of said receiving bed; and means for moving said pushers below the surface of said receiving bed during the period said card stripping and depressing element is ineffective to position a card on the card receiving bed, to thereby permit a next following card to be moved from said rotary conveyor mechanism onto said receiving bed.

2. A machine for forming separate individual record cards from a web of sheet material, of the type including means for printing successive impressions on one side of the web; means for severing the web into card lengths on each of which one of said impressions is exactly registered; and a drum type conveyor by which the severed cards are conveyed in overlapping spaced relationship; in combination with a card receiver having a receiving bed arranged in the plane of rotation of said drum type conveyor so that each card gripped thereby is moved into position for deposition into said receiving bed; means for stripping the cards in succession from said drum onto said receiving bed of said card receiver; a pivota'lly mounted card stripping and depressing element adjacent said receiving bed; means for oscillating said element in a timed relationship to the movement of said drum so that said element is moved away from and out of the plane of said receiving bed during the deposition of a card from said drum onto said receiving bed effected by said stripping means, and moved into the plane of and towards said receiving bed immediately thereafter to position each succeeding card onto the surface of said receiving bed; rotary printing means adjacent said card receiver and arranged to print on the reverse side of each card caused to be fed past said rotary printing means; card feeding means including a pair of card pushers for advancing successive cards singly from said card receiver to said rotary printing means, said pushers normally being maintained above the surface of said receiving bed; means for rendering said card feeding means operative in a timed relationship to said drum type conveyor so that a card is moved from said card receiver toward said rotary printing mechanism during the period said pivotally mounted card operating element is efiective to position a card onto said receiving bed; and camming means for moving said pair of pushers below the surface of said receiving bed during the period a card is being stripped from said drum into said card receiver while said pivotally mounted card operating element is in a position away from said receiving bed.

3. In a machine of the class described, the combination of a card receiver having a card receiving bed and a movable card stripping and depressing element so constructed and arranged adjacent said card receiving bed as to move towards and into the plane of, and away from and out of the plane of said card receiving bed, a continuously operating rotary conveying mechanism for gripping one edge of a card and, during turning, correspondingly turning the cards conveyed in an overlapping spaced relationship into position for reception by said card receiver, means including card pushers for feeding successive cards, one-by-one, by said card receiver, means for moving said card stripping and depressing element in a timed relationship to said card feeding means so as to position each succeeding card onto said card receiving bed, means for normally acting upon said pushers to maintain the same above the surface of said card receiving bed, means for rendering said card feeding means "operative in a timed relationship to said rotary conveyor so that each card is moved by said pushers from said card receiver during the periods that said card stripping and operating element is effective to position a card onto said card receiving bed, and means for camming said pushers below the surface of said card receiving bed during the periods that said card stripping and depressing element is ineffective to position a card onto said card feeding bed.
